摘要：

For geostationary communication satellites, the measurement precision of high accuracy star sensor is an important factor which affects the pointing accuracy of the satellite. Using on-orbit data from the star sensors on different positions of the satellite, we find that the variation of star sensor pointing error is related to the variation of the orbit thermal environment. We compare the thermal deformation simulation result of the installation structure of the star sensor and the on-orbit data. These two agree with each other on the direction and the magnitude of error variation. The conclusion is that the periodical thermal deformation of the star sensor installation structure is the main factor affecting its accuracy.
